Geography-Based Routing in an Ad Hoc Communication Network

The best-effort geographical multi-hop routing (BEGHR) protocol routes packets of data in an ad hoc digital radio-communication network on the basis of the current geographical positions of all the network nodes. This protocol was conceived especially for application to a network, (1) the nodes of which are equipped with Global Positioning System receivers to determine their positions, (2) the nodes of which contain environmental sensors, and (3) the main purpose of which is to collect sensory data and relay them to a central node designated as home.
